Emerald is one of the big three colored gemstones, alongside sapphire and ruby. Emeralds come in a variety of green tones ranging from yellowish-green to bluish-green, and often have a satiny "glowing" appearance in the light. Tiny inclusions in the stone actually help create this glowing satin effect. The finest emeralds were historically mined in Colombia, but today many high grade stones are also found in Zambia and Brazil, among other places. Emerald is the birthstone for May.
